SUSPENSION" DEVICE FOR vMAPS, ETC. l i

Application led November This invention relates to improvements.y in

ings, blue prints, and, in fact, any sheet maf terial to which reference is to be made, and the invention contemplates the provision of an extremely simple and inexpensive Suspension means which may be readily attached to the upper margin of a map"l or the like to be suspended and which will securely support the map when the device is adapted to suspension elements such as rods.

'/ lAnother object of theinvention is to provide a device for the purpose stated which l5 may be applied to the margin of a map or the like and securely attachedthereto without the employment of any extraneous fastening means and without any mutilation whatsoever of the map or the like.

Another object of the invention is to provide a suspension device for the purpose stated so constructed that it may be disen* gaged from the map or the likeat any time, if desired, and may be repeatedly employed for 35 an almost' indefinite period of time without losing its usefulness.

Another object of the invention is to provide a suspension device which maybe adapted to asu'spension rod' and readily applied to the rod and removed therefrom without disturbingthe suspension devices of maps or the like at either side thereof, so that any map or the like suspended by the devices may be removed and consulted and replaced without in any way disturbing any other vsuspended map or the like.

The suspension device embodying the invention is in the form of a tab adhesively at# tachable t'o the margin of a map o r the like to be suspended, and the said tabcomprises a.' head which is/indicated in general by the numeral 1, and attaching flaps which are indicated in general by the numeral 2. The head l comprises a rectangular or other suitably shaped strip 3 which-'is of pyroxyline or Celluloid, or other frelatively stiii' material.

Pyroxyline or Celluloid has beenfound to possess certain inherentcharacteristics making it particularly desirable for use in my nvention. Therefore, the use of this material is to be preferred toother substances. A strip of adhesive tape is applied over `the upperI edge of the strip 3, vas indicated by the nnmeral 4, and adhesi-vcly secured to the opposite faces of t are indicated y the numeral 5, so that the reenforcing strip 3- is completely enclosed by the folded adhesive strip. The end portions lof the adhesive strip 5, which portions are indicated by the numeral 6, are 'extended downwardly a suitable distance below the lower I. edge of the strip 3, and their adhesive-bearing,

sides are pressed againstand temporarily adhesively united to a strip 7 of. tracing linen or similar tough and yet thin and iiexiblema-- strip at its portions which.

terial having a relativelysmooth finish, the

upper' edge of the strip 7 abutting against the lower edge of the reenforcing strip 3, as clearly shown in Figures 2, 3 and 4 of the drawings, and the lower marginal portion of the said strip 7 being extended downwardly belowthe lower edges of the portions 6 of the adhesive strip 5. The strips are all in marginal registration at their lateral edges and an opening8'is formed through the portions 5 of the adhesive stripl and through the reenforcing strip- 3,. and an incision 9 is likewise formed in these strips extending between the upper side of the opening 8 and the upper'edge of the head 1 of the tab. The opening 8 is preferably located midway between the ends of the head 1 of the tab and affords means whereby, by' slightly flexing the-head of the tab above the opening at theopposite sidesof the incision 9, the' tab .may be readily applied to and disengaged from a supporting rod. opening is disposed above vthelower ed e of the stripof oelluloi-d, so that a. bridge o ce1- formation resistance.

The suspension devices will be'iplaced upon the market in the condition shown in Figure 2 of the drawings, and when it is desired to suspend a map or the like, a number of the suspension devices are applied at suitable in'- tervals to the upper margin of the map, as shown in Figure l of the drawings. In applying the suspension device, the projecting lower marginal portion of the strip 7 is grasped by the fingers of one hand and one of the flaps 6 is pulled away from the said strip until thelower edge of the strip 3 is exposed, as shown in Figure 3 of the drawings. `The device is then disposed against the margin of the map, which is indicated by the reference letter M in the drawings, in such manner that the exposedsideof the strip 7 will Contact the back of the map sheet and the upper ma r.- ginl of the said sheet will abut squarely against the lower edge of the strip 3. The said flap 6 is vthen turned down and pressed firmly into engagement with the'faceof the map sheet at the upper margin thereof, .as shown vin Figure 4 of the drawings, and as vindicated in dotted lines in Figurel 3. In pulling the flap 6 away from the strip 7 some of the adhesive coating upon the said flap 6 lwill adhere to and remain upon the face of the strip 7 so that when the iap 6 is lrestored to its original position and pressure is exerted against the opposite sides of the device,

the device will be securely anchored to thel margin of the map sheet. lAt this point it will be understood that inasmuch as-adhesive tape is employed in providing the portions 5 and 6, this tape usually comprising linen cloth and a rubber cement adhesive on one face thereof, the saine. flap 6 may be used a great number of times if the devices are transferred from one map to another. Furthermore, it will be evident thatinasmuch as the other flap 6 remains in facial contact with the strip 7 its adhesivebearing surface will be maintained in a fresh condition so that if the first mentioned Hap should lose. its adhesiveness, the device will still beuseful by employing the said other flap. o

If desired, one of the aps may be adhesively applied to one side of the map sheet and then the strip 7 may be removed and the other flap may be adhesivel pressed against the other side of the map slieet, this being a matter of choice and depending on the size 'and weight of the map to be suspended. Likewise,w ere a group of maps are to be suspended, one or more staples may be fastened through the ymaps and the .flap 6. However, it will be found that the sus ension-,device is sufficiently strong and will suciently sewith the adhesive tape.

curely held to the maps by the adherence ofv its fiaps 6 thereto, as to ordinarilyv requireno extraneous fastening means.

, As before stated, the opening 8 provides for suspension of the devices from rods and a convenient arrangement is shown in Figure 5 of the dra-wings, whereby any desired "num` 'adapting them to be engaged over the said rods. In arranging the maps, thesuspension devices will be applied to the uppermargins of the inap sheets at intervals corresponding tothe spacing of the rods 1l, and by flexing .the portions of the suspension devices at the opposite sidesof the incisions 9, the devices may be readily fitted lto lthe rods so as to ,suspend the map and so as to permit of sliding of the map, back and forth along thev rods. At intervals, for example,- every hundred maps, one of the rider bars will be placed upon the rods 11 s o that all of the maps may be simultaneously moved "by sliding this bar along the said rods.

When it is desired to remove any one of the maps suspended in the manner shown in Figure' 5, it is only necessary topull ownwardly and inwardly in a. gentle manner on the map, whereupon the portions of the suspension tab at the opposite'sides of the slit 9 will be spread apart so as to successivel disengagefrom the rod. To prevent the aps 2 from becoming detached from the head- 3 when pulled open, a line of stitches l0 can be used, as shown in Figure 2 of the drawings.. This stitching deinitely limits the extent to which thefia. s 6 may be pulledapart 'reparatory to attac ing the device 'to a inap.

urthermore when the iaps are stripped back from the insert 7-to the line of this stitching, theedge of the map canl be alined with this stitching to insure proper and accurate .positioning of the device upon the ma l Lidy device may be repeatedly clipped over lll and removed from a suspension rod without apparent injury.- I attribute this result to my discovery that pyroxyline or Celluloid' has certain peculiar propertiesi making it particularly desirablev asa substance for. the reinforcing 'strip 3. Although pyroxyline is comparatively flexible andl permits the device to be'readily-clipped over a rod, lit does `not take .a permanent deformation and always returns to its original form whenupon or off of a rod. Furthermore it permits the device to be .readily slid along a metal rod and forms an effective adhesive engagement j Having thus'describ'edtlieinvention, what I claim is:
